“We were in downtown Miami," Seddique said. “He saw two men kissing each other in front of his wife and kids and he got very angry. They were kissing each other and touching each other and he said, ‘Look at that. In front of my son they are doing that.’ And then we were in the men’s bathroom and men were kissing each other.”

Seddique was speaking to reporters to apologize on behalf of his family and disavow his son's actions.

Police say Mateen, a security guard in the Port St. Lucie area, was first engaged by a cop outside the Pulse nightclub.

Mateen was believed to have had an AR-15 style assault rifle as well as a handgun. A standoff with police lasted three hours.
